A random survey was carried out in 2000, with an error of less than 5 percent and a confidence level of 95 percent. The aim of the survey was the evaluation of the stocking rate levels of these farms in 1999 and their evolution from 1993, first year after the CAP Reform of 1992. The effects of farm size for different stocking rates are studied. Significant differences were observed (p&lt;0,05 and p&lt;0,01) between the bigger and the lesser farm sizes. This shows a higher productive intensification when the grazing surface decreases. It is to mention a high correlation between the cattle units in sheep farms (UGMo) and the cattle units in the whole sample (UGMt) (r=0,867; p&lt;0,01), as well as the association between sheep density and pig density variables (r=0,773; p&lt;0,01). On the other hand, we can observe an inverse correlation between the levels of livestock density and the farm size, which is more significant in cattle farms.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Escribano, M</style></author><author><style face="normal" font="default" size="100%">Rodriguez de Ledesma, A</style></author><author><style face="normal" font="default" size="100%">Mesías, F J</style></author><author><style face="normal" font="default" size="100%">Pulido, F</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Niveles de cargas ganaderas en la dehesa extremeña</style></title><secondary-title><style face="normal" font="default" size="100%">Archivos de zootecnia</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">dehesas</style></keyword><keyword><style  face="normal" font="default" size="100%">Grazing</style></keyword><keyword><style  face="normal" font="default" size="100%">Stocking rate</style></keyword><keyword><style  face="normal" font="default" size="100%">Structural analysis</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2002</style></year></dates><volume><style face="normal" font="default" size="100%">51</style></volume><pages><style face="normal" font="default" size="100%">315-326</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This work analyzes the data collected from 143 sheep and/or cattle farms, representatives of the Extremaduran dehesa (semiarid grazing areas of the SW of Spain).

The polysaccharide has a backbone of P(1-4)- and P( 1-3)-linked glucopyranosyl, P(lk4)-linked xylopyranosyl, and (1-4)- and (1-6)-linked galactopyranosyl residues. Arabinofuranosyl, rhamnopyranosyl, and some xylopyranosyl and galactopyranosyl groups are present as nonreducing end units. Glucopyranosyluronic acid side chains are attached at 0-2 of some xylose residues. The anomeric configurations of the different glycosyl groups were determined by a study of the chromium trioxide oxidation of the acetylatcd polysaccharide and by nuclear magnetic reasonance spectra of the methylated polysaccharide.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">PGPG</style></notes></record></records></xml>
